Superabsorbent Polymers Usage Tips
Usage Tips for Waste Lock® Superabsorbent Polymers
Since all waste streams are different, we suggest that the user experiment with a laboratory beaker (or similar) or waste and some polymer to determine the proper ratio of polymer-to-waste.
These polymers absorb as a result of a diffusion gradient that is created on the particle’s surface during a process of partial Sodium neutralization. This diffusion gradient means that the polymer will absorb more of less ionic solutions. In other words,
Deionized Water - Waste Lock® 770 will absorb 500-600X it’s weight.
1% NaCl in Water - Waste Lock® 770 will absorb 45-55X it’s weight.
2% NaCl in Water - Waste Lock® 770 will absorb 35-40X it’s weight .
These absorbency ratios only approximate the potential actual performance in a real waste treatment situation. Other effects include:
For these reasons, we strongly suggest some laboratory or pilot-scale tests be performed to determine the correct ratio of polymer-to-waste.
